Variations on a Rococo Theme for Cello and Orchestra, op. 33

The Variations on a Rococo Theme, Op. 33, is a concertante work for cello and orchestra by Pyotr Ilyich Tchaikovsky. It is the closest he ever came to writing a full concerto for cello and orchestra. The style was inspired by Mozart, Tchaikovsky's role model, and makes it clear that Tchaikovsky admired the Classical style very much. However, the Theme is not Rococo in origin, but actually an original theme in the Rococo style.
Tchaikovsky wrote this piece for and with the help of Wilhelm Fitzenhagen, a German cellist and fellow-professor at the Moscow Conservatory. Fitzenhagen gave the premiere in Moscow on November 30, 1877, with Nikolai Rubinstein conducting. This was perhaps the only hearing of the Variations as Tchaikovsky wrote the piece, until 1941, when it was played in Moscow without Fitzenhagen's by-then-standard emendations.
